23 Claims. (Cl. 226-97) Thisinvention relates to amachine'for filling liquids into containersand is particularlyadapted to the filling of gasolen'e or othervolatile or nonvolatile liquids, into thecommercial five gallon can. r

In most previous machines for filling liquids into containers of this type it has been the general practice-to weigh the charge of liquid going into each container, and where machines of high capacity were employedthisnecessitated a number of weighing devices equal to the number of filling stations on the machine, and it further required an individual adjustment of each weighing device at each filling'station inforder to have each container receive the correctcharge of liquid, which has provenfltolbe very difiicult'task and keep all of the fillingstation's adjusted to 'deliver' like quantities throughout a day run, or in fact for any relative period of operation.

Another difiiculty with prior machines has been to keep the numerous valves necessary to the operation of the filling devices, from leaking and wasting large amounts of liquid which has been a monetary loss as well as a dangerous condi- 25 tion of operation.

Through extensive experiments and development work I have succeeded in evolving an appa ratus for handling and filling liquids such as the commercial gasolene, into five gallon containers in a manner that has eliminated the majority 'of the valves heretofore necessary; has taken care of leaky valves, if theyoccur, in a manner to save every bit of the leaking material and carry it back to the main supply; as well as taking care of the usual drip from closing valves and direct ing it backto the main supply.

I have provided means for preventing a measuring chamber from being tipped to discharge its contents if a can is not present, and to prevent the opening of the valve to that measuring chamber if it has not been discharged so that this particular chamber will not be tipped to discharge its charge nor will it receive more. liquid until a container is present to receive the chargeL I have also provided measuring chambers that are pivoted to discharge their contents; that have a well for a small surplus of liquid so that the i measured charge delivered to the containers may be varied by slimply controlling the tipping of the measuring chambers; that have an area of reduced surface when the chamber approaches the complete fill so that the measured charge is very accurate compared to'former devices, and there is also a tail extension on each measuring chamand with other means for preventing the delivery ber to catch the dripfromthe valve at the closing thereof or from a leaky valve.

' I have also provided a casing to surround the measuring chambers so that all fumes from the gasolene will be trapped and led back to the. main gasolene supply and thus kept out of the room and thus reduce to some extent the natural fire hazard in handling this type of liquid.

It is therefore a principal object of the inven-' tion to provide a machine for filling liquids into 10 positioned containers by means of tilting measuring devices that carry a measured charge greater than the charge delivered to the containers.

It'is also an object of the invention to provide a machine for filling volatile liquids into posi- 15 tioned containers by means of tiltable measuring chambers that are enclosed in a substantially tight casing .withthe onlyopening being the discharge nozzle to the container. I i

It is also an object of theiinventionto provide a machine for filling volatile liquids into positioned containers wherein means are provided for preventing the tipping of a measuring chamber if a container is not positioned thereunder of more liquid to that measuring chamber until its charge has been delivered to a container.

It is also an object of the invention to provide a machinevfor filling volatile liquids into positioned containerswherein the measuring chamber delivering the charge maybe controlled1 in its tipping to deliver more or less of its charge; according to the temperature of the liquid being handled; V v t It is also anobject of the invention to provide a filling machine for delivering measured charges of a liquid to positioned containers wherein the opening of the valves delivering liquid to the measuring chambers are controlled by the presence of a container'for each measuring chamber.

It is also an object of the invention to provide a filling machine for delivering measured charges of a liquid to positioned containers wherein the delivery of the liquid from the measuring chambers to the containers is con-t trolled by the presence of acontainer. o

It is also an object of the invention to provide a machine for filling volatile liquids into positioned containers wherein a supply tank is positioned in the top of the machine so that supply will flow by gravity to the measuring chambers and with an overflow tank below the supply tank for accumulating the overflow liquid and with means for then returning the overflow liquid to the main supply, all of the said operations being conducted in substantially closed spaces.

With such objects in View as well as other objects and advantages which may be inherent in the invention, consisting in the parts and combinations hereinafter set forth and claimed, it is understood that the several necessary. elements parts and combinations constituting the same may be varied in their proportions, placement and general arrangement without departing from the scope and nature of the invention, and'in order to make the invention more easily understood there are shown in the accompanying drawings means and mechanism for placing the. same in concrete form, without limiting the improvements in their applications to the particular construction chosen to illustrate the invention.

The drawings herewith are not necessarily drawn to scale neither do they necessarily represent to best engineering practices in the construction' of machinery of'this type, and some parts may be more'or less, exaggerated in their proportions and placement to better illustrate the operative principles involved. v

. Fig. 'is a detached detail of the control mech;

anism that controls the opening 'of the valves to admit liquid to themeas'uring chambers.

Fig. 5 is a detached detail or one of the devices for tilting the filled measuring chambers.

The means and mechanism embodying this invention consists of a base member 1, set in a co n crete foundation below the floor level. Secured directly on this base member is the overflqw tank 2. Extending up from the base member is a central drive shaft 3 extending to the top of the room and having its upper end secured in a suitable bearing member 4;. Positioned directly over the overflow tank 2 and centrally maintained by the shaft 3 is a turret member 5, which carries around its cen ter a drain tank 6 and around its'periphery a series of container supports 60.. Aside from its support on the shaft 3, the turret member 5V is also supported by the rollers 7 riding on the circular cams'8; The container supports 6a are controlled in their, vertical movements by the circular cam 9.

Located directly over the turret member 5 is another turret member 10 maintained concentric by the shaft 3 and carrying around its periphery a series of casings 11 in which is mounted a series of tiltable measuring chambers 12. Each 7 measuring chamber is pivoted near its center'as is for filling the liquid into the chamber and the. opening 122 is for discharging the liquid fromthe chamber, The top covering of the chamber has a concaved or depressed center as at 123 which is i just below full level of the liquid, when the chamber is filled and tends to restrict the surface to increase the charge delivered to the containers.

Each measuring chamber carries a tail extension 126 which has continual flow contact with the casing 11 so that any drip from the valves will.

be directed to the casing. The drip flowing from the tail extension 126 down through the pipe line 127 to the tanks 6 and 2 from'where it is pumped back to the main supply as has been mentioned. Each measuring chamber is supplied with liquid by means of thevalves l4 and the cam controlled valve stems each of which is provided with the arms 16 with rollers on the ends riding on the circular camlfl. [Arranged centrally in the top of the apparatus is a general supply tank 18' receiving supply of liquid from the pipe line 19 con-.

trolled by the float valve 20.

. Arranged at the left of Fig. 2 will be seen the cQl'ltrol m a m 3 ak n f th il ing: of the measuring chambers through the presenceof a container. A sweep arm 2 1 ismoved; by a. container which, through the links androds shown; connect with a short section 33 of the cam track 22 andinove it so that when the rack bars 23 with the cam rollers 24 reach the point where the measuring chambers should be tilted to deliver their charge to a positioned container, thechamber will be tilted and placed in the position shown at the right of Fig. 2 where the charge has been delivered to the container and a little puddle of liquid remains the pocket 125. The tilting of each measuring chamber is accomplished by short section of it, will be moved to present an elevated section 29 over which the "rollers on the ends of the arms 16 will ride and'thereby lift the valvearms 16, the valve stems and permit liquid to flow into the measuring chamber, if no container is present no liquid is released, and likewise'if no container is present when it comes.

time to tilt the measuring chambers the tilting will be prevented. V I

Fig. 1 shows a feed chute 30 for deliveringcontainers to the machine and a discharge disk 31 for taking' the filled containers away from the machine. V

Operation The operation of the machine would be substantially as follows if built according'to the drawings but may operate somewhat differently it built according to any permissible variations from that shown.

The first act in the operation of the machine would be to fill each measuring chamber with liquid. This is accomplished by simply holding the lever 28 outward as it would be held if cans IOI.

were present on the lifting plates 6a. As the machine rotates then each measuring chamber 12 will receive a charge of liquid, but none will be discharged because no containers being present the mechanism controlling the tilting of the measuring chambers will be inactive and the machine would continue to rotate with the filled.

further advance of the remaining cans until its.

return to the beginning of the feeding stroke.

The rocker 32 is pivoted at 128, the pivot shaft having a fixed arm 129 connected to a link 130 which in turn is connected to the crank arm 131 which is rotated by a sprocket 132 that may be driven in timed relation with the approach of the lifts 6a from any suitable meansand may be driven from the shaft on which the disk 31 is mounted by means of a sprocket 133 and chain 134. The continuous rotation of the crank arm 131 acting to rock the member 32 back and forth and at each movement placing a can on the lift 6a and through its arcuate face 135 which rides in front of the advancing cans in the chute 30 holds them from further advance until the rocker is fully retracted when the column of cans will move up until a can rests in the pocket of the rocker 32 when it will be positioned on a lift 6a at the next rocking movement of 32. The crank arm 131 will make one complete revolution to one eighteenth revolution of the turret carrying the lifts 6a, since there are eighteen lifts of the machine. This will feed a can each time a lift reaches feeding position.

As the. cans advance into their circuit they will first engage the control lever 21 at position B: Fig. 1 which will operate the rods and levers as in Fig. 3 and move the rack bar 23 causing a tilting of the chamber 12 to discharge its'contents into the positioned can. The movement of the rack bar is accomplished by the swinging of the cam switch 33 Fig. 1, and Fig. 3 as shown in dotted lines. When it happens that a can is not positioned on one of the stations this switch 33 is not moved but remains in the position of the full lines which causes the cam'roller-24 to ride on the outside of the cam as shown at 34.

By an examination of the plan of this cam in Fig. 1 it will be seen that it is not concentric its entire way around the circle but that a portion of it is on a larger circle than the other portion.

The position of the measuring chamber 12 at the left of Fig. 2 is not technically correct. In order to show the tilting mechanism of Fig. 3 in this view and at the same time show the measuring chamber 12 in an upright or filling position the chamber 12 is shown in its position just approaching the switch 33, it being understood that the chamber 12 isupright from station A to station B.while moving in a counter clockwise direction. Likewise on the right of Fig. 2 theparts are not in the technically correct positions. At station A the switch 28 acts to move the cam member 29 onto the top side of the cam 17 so as to raise the lever 16, and thereby open the valve 14 to admit gasolene to the chamber 12. In order to show the chamber 12 in a tilted position as at the rightof Fig. 2 it would not be proper toalso show the cam member 29 as in the position of Fig. 4 because'then gasolene would fiow before the chamber 12 was tilted upright to receive it. The member 29 is there--. fore shown just back of the arm 16 which will be moved to open the valve as soon as the chamber 12 is tilted to the upright position.

After tipping, the containers remain in a tipped or discharging position for. almost half the circle of travel, or until they reach the switch 35 when the travel of the cam roller 24 will move from the switch 35 and pass into the cam track 37 thereby moving the rack bar to position the chambers 12 upright to receive anew charge of liquid. The presence of the container acting to operate the rack bar at this station, through having positioned the roller in or'outside of the cam track.

Just as soon as the containers have been righted for receiving a new charge the presence of the filled can on the lift 6a acts to operate the fill control mechanism operated by the lever 28' which .will lift the valve arm 16, open the valve and permit liquid to flow into the chamber 12 during its travel from position A to position B, where it will again be tipped and discharged if a container is present. pivoted at 136 and is operated by the mechanism at the left of Fig. 2 and that shown in Fig. 3. The switch member 35 is pivoted at 137 andiis free to be moved by the rollers passing. If the rollers 24 are moving in. the cam groove 44 as they approach the switch 35 it will be opened from the position shown in Fig. 1 and remain open so long as rollers 24 are moving in cam 44, but when a roller like 34 moving outside the cam 44 approaches the switch 35 will be moved.

to the position of Fig. .1 some roller 34 can pass into the cam groove 37.

The cam member 29 is pivoted at 138 Fig. 1.

and is held in the position of Fig. 4 on top of the cam 17 so long as cans. are regularly supplied to the machine but when a can is missed then this cam member 29 is positioned away from thel cam 17 and rests as shown by dotted lines in Fig.

1 whichwill permit the arm 16 to pass this point without being lifted so that no gasolene will'be supplied to this chamber 12 which is already full.

This cycle of operation continues as long as. cans are delivered to the machine. The absence.

The change in the cam contour of the cam track 17 to effect theopening of the valves 14 to admit liquid to the measuring'chambers is" accomplished as follows. I

Each time a can passes it contacts with the lever 28 which in turn through the levers and rods shown actuates the cam switch 29 which is moved over the cam 17, then as the rollers on the arms 16 approach they ride over the switch 29 and are thereby elevated which opens the valves 14. The friction of the valve stems 15 in the stuffing box is sufiicient to hold the valves open until they are closed by a fixed bracket 38 under which they ride which moves them down to the closedpositions. i

The Whole turret assembly is rotated by means of the worm and worm wheel shown under the tank 2. The liquid accumulated in the tank 2 is carried away through the pipe 39 to a circulating pump for reuse. I will now describe the manner in which the fill of the containers may be varied to suit changes in temperature or other prevailing conditions that The cam switch 33 is may require more or less liquid to be delivered to each container.

The surplus puddle of liquid retained in each of the measuring chambers indicated at 125 has been referred to as remaining in each chamber after the container has received its predetermined charge of liquid. This excess of liquid is delivered to each measuring chamber each time it is filled, or rather we might better say this small surplus remains in each chamber as it is refilled to serve as a supply when it is desired to deliver an excess of liquid to each container to take care of differences in temperature durina days run, or to receive an excess of liquid retained by the measuring chamber if a less amount is delivered to each container. 7

In this machine one outside adjustment of the cam track controlling the tipping of the measuring chambers 12 serves to control an additional or a less tipping of each chamber as it passes through the adjustedsection. This mechanism is illustrated at the top of Fig. l. 40 and 41 represent adjusting screws operated by the hand wheel 42 and bevel gears shown. The screws 40 and ll have no axial movement but move the long sleeves 43 which are fastened to the short section of Cara track as thus moving the section of cam track' is radially one way or the other to regulate the fill of liquid passing into each container.

In the construction and original adjustment of the measuring chambers 12 they are all adjusted to give exactly the same quantity of fill to each container, Within a very small fraction of an ounce, so that by adjusting the short section of cam track just described each chamber is tilted in exactly the same mariner'and thereby the charge going into'each container to suit operating conditions is controlled.
